How to Develop Fly-Through Animations

Fly-through animations are a creative way to visualize inside 3-dimensional plots. In our latest Tips & Tricks video, I demonstrate how to develop these fly-through animations. The trick is, once you have your results stored in your data set, you need to define a results parameter that will be used to govern a filter of […]

COMSOL Version 6.1 Least-Squares Fit Function

Technology continues to evolve, making our lives a lot easier in many ways. And, when it comes to Multiphysics, the Least-Squares Fit function of COMSOL 6.1 is no exception. Before this function existed, engineers had to develop their own coding to perform this type of fitting. But, in our latest Tips & Tricks video, we […]

User-Defined Material Library

User-defined materials provide the flexibility needed to design models using a combination of existing material properties and properties defined by the user. These material properties can also be included in a user-developed material database for easy access to frequently used materials. Users often spend significant time developing models with material properties not available in the […]

Anisotropic Material Properties

Many of the simulations we have developed through the years include materials that behave anisotropically. This class of materials has different material properties in different directions. This anisotropy often needs to be included in computational models to achieve the desired level of accuracy in the simulation outputs. If the material coordinate system of the anisotropic […]

Continuity Pairs for Electrical and Thermal Contact

Thermal stresses are an important design concern for many engineering applications.  When temperatures change, materials can deform or warp leading to the build-up of internal stresses even without the presence of external constraints which can further increase thermal stresses.  Modeling and simulation can calculate the deformations, stresses and changing contact pressures using thermal-structural interaction techniques.  […]

Watch Out for Transparent Layers

Many engineers solve heat transfer challenges regularly. Over the last 20 years, AltaSim has developed hundreds of simulations for our clients that include heat transfer as a component. This Tip comes from our experience in solving a heat transfer problem that included thin layers of different materials. Solid elements are the most widely used type […]
